[2005] Problems with proccess.start("mailto:")

[ovanwijk]

As stated above i have some trouble whith this.
Not that it dont works but . . . . i want to be able to send a LOT of mails @ the same time under bcc.

My code


Code:

Dim counter As Integer
Dim Tstring As String = "[email protected]"
Do Until counter = 1000
Tstring = Tstring + "," + "[email protected]"
counter += 1
Loop

Toevoegen.tools.StartDefaultMail("[email protected]", Tstring)

Where the do loop should represent the amount of email addresses


Code:

Public Sub StartDefaultMail(ByVal MailTo As String, Optional ByVal BCC As String = "")

        Try
            Process.Start("mailto:" & MailTo & "?bcc=" & BCC)

        Catch e As Exception
            MsgBox("Couldn't start default email application")

        End Try
    End Sub

(when i use e.message as exxeption then it gives the message: Acces denied)


And here the startdefaultmail

When i start the proccess with more as 150 email addresses it wont start.
Its possible to make my own mailclient ofcourse but its quite much since it should be able to send newsletters with pictures and such things (and it must be used by computer noobs) so i prefer giving them their own mail client.

But my problem is that i cant send that much mails @ the same time.
Is there any solution for this?

Ah, this makes me nostalgic. This was the subject of my very first post on this forum. I asked the very same question for the very same reason. I wanted to send a single e-mail with a lot of recipients.

The issue is nothing to do with e-mail specifically. It appears that the Process.Start method doesn't accept "path" longer than just over 2000 characters. I didn't ever determine the exact maximum but I would guess 2047 or 2048. I guess when they implemented Process.Start they didn't take long mailto URLs into account. I never found a proper solution to this. You may be able to find an API function to use instead but I didn't look that far. I just broke up any recipient list that was too long and created multiple messages.

Hehehehe thats funny indeed.

And i tried system.net.mail
But the problem is that the user must type HTML code(no i dont gonna write my own HTML editor :P) and its not a normal way to place things like images from your mail attachment into your email message.

Isnt it just possible to add contacts to your default mail client and then send a whole contact group a mail or something like that?

Ok people a new problem when i solved this.
Instead of using "mailto" i used something else.

 Dim oApp As New Outlook.Application
        Dim space As Outlook._NameSpace
        'Dim Folder As Outlook.MAPIFolder

        space = oApp.GetNamespace("MAPI")
        space.Logon(Nothing, Nothing, True, True)

        Dim mail As Outlook._MailItem
        mail = oApp.CreateItem(Outlook.OlItemType.olMailItem)
        mail.To = "[email protected]"

        Dim counter As Integer
        Dim Tstring As String = "[email protected]"

        Do Until counter = 10
            Tstring = Tstring + "," + "[email protected]"
            counter += 1
        Loop

        mail.BCC = Tstring
        mail.Body = " Hey"
        mail.Subject = " Test"
        mail.Save()

This works great. It places the email i make in the folder "Drafts" where they can freely edit the email. But the problem is still that it is not possible to send it to a LOT of people @ the same time. So my question is. Does someone know how to get mail from your outlook into a mail inside vb(Outlook._MailItem). This is because i can send mails then to only 20 addresses as many times i want to (when i am out of addresses ofc).

What you're doing is all well and good but it requires your user to have Outlook, so it won't work with any other mail client. If you know that your users will all have Outlook then that's not a problem, but if you don't know that then it's a big problem.
